18 | the FrameGraph, only the entities whose QGeometry bounds intersect with the camera |
19 | frustum, i.e. the view of the camera, are drawn. If QFrustumCulling is not present, |
20 | all drawable entities will be drawn. The camera is selected by a QCameraSelector |
21 | frame graph node in the current hierarchy. Frustum culling can save a lot of GPU |
